IMPROVED DEVICE FOR RIN GIN G STREET-CAR BELLS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that 1,.CHARLES CARR, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and usefrl Improvements in Signaling Apparatus for Cars; and I do hereby declare that the following is a full and exact description thereof, reference being had to the, accompanying s and to the letters of reference marked thereon. With reference to the drawings Figure l is a longitudinal sectional elevation of a street-car, illustrating the nature and application of my improvement.

Figure 2 is a similar transverse sectional elevation.

Figure 3 is an enlarged view of the apparatus, corresponding to fig. 1.

Figure 4 is an enlarged sectional view, correspond ing to fig. 2. I

Figure 5 is aplan of a portion of the apparatus.

Figure 6 is a sectional view of one of the guide-pulleys for the strap-pulls.

Figure 7 embraces two views of one of the intermediate levers between the spring-rod and the hell or other indicator,

Figure 8 embraces two views of the other lever for like purpose, but adapted to the functions required at the opposite end of the car or apparatus.

Like letters refer to the same or corresponding parts in all the figures.

In figs. l, 2, and 3 may be seen two signal bells, a, one arranged at each end of the car. The driver (when horses are used) ordinarily V the conductor, and avoid generally the inconveniences and evils arising from the promiscuous signaling of the driver by the passengers, not the least of which. arises from the fact that the horses become accustomed to stop and start at the. sound of the signal-bell at the drivers end of the can. One object, therefore, of this improvement is to secure to the conductor exclusive control of those signals in obedience to which the driver stops and starts his car, and also in obedience to which the horses, by constant use, acquire the habit of stopping and starting.

Intermediate between the bells n is arranged a rod, b, so as to slide freely in the direction of its length toward and from the points of location of the bells.

' This rod is provided with springs, k, whereby it is made to return to its central position on being released,

stands beneath the one bell, and the conductor beneath the other. Tire obafterit is made' to slide in either direction. 1 will here observe that this rod need not necessarily be sustained in slides, as any other means may be used which will allow it to perform like functions.

Tire means for giving the longitudinalmovementto rod 1) are clearly shownin figs.4 and 5, and consrst of the strap-pulls a, guided by the pulleys h and y. The pulleys h and j are carried in any suitable stat onary stands, i. The rod 1) may also receive rts longrtudinal motion by means of straps and connections, j and p, at either end of the car. Tire straps or connections f and 11 may be attached, in some cases, drrectly to the rod, but ordinarily I interpo'se the levers c and (I, one at either end respectively.

By means of said levers c and ii I am frrrnrshed wrth convenient facilities to reverse, as occasrorr requires, the movement derived from the longitudinal movement of rod 7), in its application to produce the srgnal by striking the bell, or operating such other rndrcator as may at any time be substituted for: the bell.

Tire rod 7), in all cases, should be of a rigid nature. so far that its motion may surely be communicated rn either direction from the points of attachment of the the pulls a, which always give movement to the rod in one direction only. Tire materialsto be used rn the construction of the several parts may be such as are ordinarily employed in the art, or may suggest themselves to the maker as best adapted to the purpose.

The operation may be explained as follows:

It being assumed that the part of fig. 5 at the bottom of the drawing is toward. the right hand in figs. 1 and 3, then, if a passenger draws the pull a, (see hgs. 4 and 5,) the rod b is moved to the left in figs. 1 and 2; this motion tilts the lever c, fig. 3, draws the connection e, and causes hammer o to strike its hell it, under which the conductorstands. The conductor then pulls the strap p, fig. 1, which tilts lever c in the opposite direction, and through it moves the rod b rn the opposite direction, tilting lever d, drawing connection f, and causing hammer o to strike bell a, over the drivers head, thus signaling him; the springs F always returning, by their recoil, the rod 11 to its central position. If the driver desires to signalize the conductor. he draws the connection f, figs. l and 2, toward the right hand of the drawing, tilting lever d, moving rod b, tilting lever 0, drawing connection e, and causing hammer o to strike hell it. When the car stops and starts in the opposite direction, and the driver and conductor consequently exchange positions, then the connections 0 and f are disconnected from the lower ends of levers o and (l, and connected to the tops of the same levers, and all is right to operate 'as before with reference to the driver and conductor.

It will be observed that the straps or pulls a are conveniently arranged within reach of the passengerswhile seated. They may be either at their backs upon the side of the car, or as shown in fig. 2, while, for the conductors use, to signal the driver from within the car, a private pull, arranged to move the rod b in a direction opposite to that by means of pulls a, may be furnished in the top of the car, not easily accessible to the passengers.

Thus having described my improvement,

What I claim as my invention, and desire to secure by Letters Patent, is as follows-- 1. The employment of the spring rod b, in combination with the bells, or equivalent signal, at substantially as described.

2. The arrangement of the strap-pulls a, in combination with the spring rod 12, and in relation to the carseats, substantially as described.

through pulls a, or their equivalent, conveniently ac-' cessible to the passengers within, the signals can be given at one end only of the car, while, by the same combination of apparatus with the car, provision is also made for convenient and direct signals between the conductor at one end and the driver at the other end of the car, substantially as set forth.

CHARLES CARR.
